摘要:
目的：对比三维多回波恢复梯度回波（3D MERGE）、三维可变反转角快速自旋回波（3D SPACE STIR）序列在腰椎间盘突出症（LDH）检查中的应用效果。方法：选择2020年1月~2022年11月收治的135例LDH患者，回顾性分析患者临床和磁共振成像（MRI）资料，所有患者均接受常规MRI扫描及3D?ERGE、3D?PACE?TIR序列扫描，对比3D?ERGE、3D?PACE?TIR序列测量神经根直径的一致性，评价两种序列的图像质量参数［信噪比（SNR）、对比噪声比（CNR）］、图像清晰度评分。结果：3D MERGE和3D SPACE STIR序列测量的L3~S1神经根直径比较差异无统计学意义（P>0.05），且两组序列测量的L3、L4、L5和S1直径均显示出较高相关性（r=0.957, 0.986, 0.975, 0.972, P<0.05）；3D MERGE序列的SNR及CNR均高于3D SPACE STIR序列，神经根显示分级、图像清晰度评分优于3D SPACE STIR序列，差异有统计学意义（P<0.05）。结论：3D?ERGE、3D?PACE?TIR序列在LDH神经根直径测量中具有极高一致性，3D?ERGE序列较3D?PACE?TIR序列能够更清晰显示神经跟的解剖形态，图像质量更好。
Abstract:
Abstract: Objective To compare the performances of 3D MERGE sequence and 3D SPACE STIR sequence in detecting lumbar disc herniation (LDH). Methods The clinical data and MRI data of 135 LDH patients admitted between January 2020 and November 2022 were analyzed retrospectively. All patients were examined using conventional MRI, 3D MERGE sequence and 3D SPACE STIR sequence. The consistency of 3D MERGE sequence and 3D SPACE STIR sequence in measuring the diameter of nerve root was analyzed, and the image quality parameters ［signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR)］ and image definition score of the two sequences were evaluated. Results There were no statistically significant differences in L3-S1 nerve root diameters measured by 3D MERGE sequence and 3D SPACE STIR sequence (P>0.05), and the diameters of L3, L4, L5 and S1 measured by the two sequences showed high correlations (r=0.957, 0.986, 0.975, 0.972, P<0.05). Compared with 3D SPACE STIR sequence, 3D MERGE sequence had higher SNR and CNR, scored better on image definition, and displayed nerve root more clearly (P<0.05). Conclusion 3D MERGE sequence and 3D SPACE STIR sequence have high consistency in the measurement of LDH nerve root diameter. 3D MERGE sequence can display the anatomical morphology of nerve root more clearly as compared with 3D SPACE STIR sequence, and the former one has higher image quality.
